What Is This Bot?

The Polymarket Market Maker Bot is an automated keeper that provides liquidity on the Polymarket CLOB (Central Limit Order Book). It continuously places and cancels orders around the midpoint price, acting as a market maker to earn the bid-ask spread while helping other traders execute their trades.

Whether you're a prediction market enthusiast or a DeFi trader looking for passive income, this bot runs 24/7 to capture market-making profits on Polymarket.

5 Advantages for Traders

#	Advantage	Why It Matters
1	Passive Income	Earn the bid-ask spread automatically. Your capital works for you while you sleep—no manual trading required.
2	24/7 Automated Trading	The bot monitors the order book and rebalances orders every 30 seconds (configurable). No need to watch charts or place orders manually.
3	Two Professional Strategies	Choose AMM (concentrated liquidity style) or Bands (multi-tier order placement). Each strategy has tunable parameters for your risk/reward profile.
4	Full Control & Transparency	Open-source code, configurable spreads, depth, and collateral limits. You decide how much capital to deploy and how tight your quotes are.
5	Graceful Shutdown	On exit (SIGTERM), the bot cancels all open orders and exits cleanly—no orphaned orders left on the book.

Quick Start – Run the Bot

Requirements

Python 3.10
A Polymarket account with USDC (Polygon)
A condition ID for the market you want to make

1. Install

./install.sh

This creates a virtual environment and installs dependencies.

2. Configure Environment

Create a .env file (see .env.example):

PRIVATE_KEY=your_private_key
RPC_URL=https://polygon-rpc.com
CLOB_API_URL=https://clob.polymarket.com

3. Configure Market & Strategy

Edit config.env:

CONDITION_ID=0x...   # Hex condition ID of your Polymarket market
STRATEGY=amm         # or "bands"
CONFIG=./config/amm.json   # or ./config/bands.json

Adjust strategy parameters in ./config/amm.json or ./config/bands.json as needed.

4. Run

./run-local.sh

Docker (Alternative)

Strategy Overview

Strategy	Description
AMM	Concentrated liquidity style—places orders at multiple price levels with configurable spread, delta, and depth. See docs/strategies/amm.md.
Bands	Multi-band strategy—maintains orders within specified price bands and size ranges. See docs/strategies/bands.md.

The bot syncs every 30 seconds by default: it fetches the midpoint, computes expected orders, cancels outdated ones, and places new ones.
